I just recently purchased a new server and setup the drives for a Raid 5. The total drive space is 3.5 TB. When I get to the part of the Windows 2008 R2 installation where Ineed to partition the drive it only allows me to choose 2TB of the drive for the primary partition. The other part of the drive is unalocated space. What am I doing wrong? Also, if I proceed with the installation I cannot format the remaining 1.5 TB of space to a usable partition.
